Quantification of the fate of residue N is essential in low-input tropical cropping systems for the development of management practices that optimize N-use efficiency. The recovery of N from 15N-labeled leucaena (Leucaena leucocephala (Lam.) de Wit) and dactyladenia (Dactyladenia barteri (Hook f ...

Recovery of leucaena and dactyladenia residue nitrogen15 in alley cropping systems
In tropical cropping systems with few external imputs, efficient management of mineral N derived from added organic residues is essential for the proper functioning of the system. We studied the dynamics of mineral Nitroden (N) in the top 100 cm of soil with a system tensiometers and suction cups...

Sustainable resource management is the critical agricultural research and development challenge in sub-Saharan Africa. The accumulated knowledge on soil management gathered over the last 10 years, combined with solid crop improvement and plant health research at farmers’ level, has brought us to ...

The IITA in its research for sustainable soil fertility management has passed through several stages during which legume-based systems were always at the forefront. Alley cropping has N yields of more than 200 kg ha-1 with 50% N2 fixation. In the case of Mucuna cover cropping, the ecological bene...
